El objetivo de este estudio fue proponer una estrategia de monitoreo hídrico comunitario para mejorar la gestión del río Jorco ubicado en el cantón de Acosta. Se monitoreó la calidad del agua en la parte alta, media y baja de la microcuenca durante la época lluviosa, utilizando dos índices de calidad (ICA) fisicoquímicos: el Holandés y el Calvo-TEC; así como uno biológico: el BMWP-CR. Los indicadores de calidad de turbiedad, alcalinidad, amoniaco, nitrógeno amoniacal, nitratos, y coliformes fecales superaron los límites de permisibilidad en algunos muestreos; sin embargo, el oxígeno disuelto mostró que existen buenos niveles de oxígeno para la recuperación del río. La demanda bioquímica de oxígeno fue baja, indicando una carga orgánica baja y los macroinvertebrados mostraron un ecosistema acuático degradado. El ICA Holandés sobrevaloró la calidad del agua con respecto al ICA Calvo-TEC. Este último mostró resultados más realistas debido a que utiliza más indicadores de calidad, ya que este parte de las condiciones ambientales y la normativa costarricense. Por su parte, el ICA BMWP-CR reveló una contaminación extrema durante el mes de mayor lluvia. Se concluyó que existe un problema de contaminación en el agua del río cuyas causas principales pueden ser por la falta de cobertura boscosa en las zonas riparias, la expansión del cultivo de café, el vertido de aguas residuales domésticas y las actividades ganaderas. Por lo tanto, se propuso al consejo municipal un plan de acción y validado con ellos, con el fin de mejorar la calidad del agua con participación de diferentes actores de la zona.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract s The profound deficiencies that the country faces in water management policies are reflected in the physicochemical, microbiological and biological contamination of national rivers. The objective of this study was to propose a community water monitoring strategy to improve the management of the Jorco River located in the canton of Acosta. The quality of the water in the upper, middle and lower part of the micro-basin was monitored during the rainy season, using two physicochemical quality indices (ICA): the Dutch and the Calvo-TEC; as well as a biological one: the BMWP-CR. The quality indicators of turbidity, alkalinity, ammonia, ammoniacal nitrogen, nitrates, and fecal coliforms exceeded the permissibility limits in some samples; however, dissolved oxygen showed that there are good levels of oxygen for river recovery. Biochemical oxygen demand was low, indicating low organic load, and macroinvertebrates showed a degraded aquatic ecosystem. The Dutch ICA overestimated the quality of the water with respect to the ICA Calvo-TEC. The latter showed more realistic results because it uses more quality indicators, since it is based on environmental conditions and Costa Rican regulations. The ICA BMWP-CR revealed extreme contamination during the month of greatest rainfall. It was concluded that there is a problem of contamination in the river water whose main causes may be due to the lack of forest cover in the riparian zones, the expansion of coffee cultivation, the discharge of domestic wastewater and livestock activities. Therefore, an action plan was proposed to the municipal council and validated with them, to improve water quality with the participation of different actors in the area.]]></p></abstract>
